ObjectiveTo observe the clinical characteristics of retinoblastoma (RB) in Southwest China.MethodsA retrospective clinical study. From January 2010 to December 2017, 66 RB patients diagnosed in Ophthalmology Department of West China Hospital of Sichuan University were included in the study. All the patients underwent ocular B-ultrasound, orbital CT or MRI examination. Ten patients underwent RetCam examination at the same time. Twenty-nine patients were diagnosed by histopathological examination, and 37 patients were diagnosed by clinical symptoms and imaging examination. According to whether the tumor invaded the orbit and optic nerve, it could be divided into extraocular stage and intraocular stage. Intraocular tumors were divided into A-E stages according to the international intraocular RB classification. Treatments were performed according to different stages. The general information, age at diagnosis, course of diseases (the time between onset symptoms and diagnosis), causes of visiting a doctor, classification, treatment methods and eyeball preservation rate were retrospectively analyzed.ResultsPatients all came from Southwest China (56 patients from Sichuan Province, 2 patients from Yunnan Province, 2 patients from Guizhou Province, and 6 patients from Tibet). The permanent residence were identified in 43 patients, including 27 patients (62.8%) from rural areas. There were 38 males (57.6%); 50 unilateral tumors (75.8%) and 16 bilateral tumors (24.2%); 51 first-visiting patients (77.3%) and 15 re-visiting patients (22.7%). The average diagnostic age of first-visiting patients was 20.9±14.4 months, with 23.2±14.7 and 11.2±7.6 months for unilateral and bilateral tumors, respectively. There were 41 patients had definite course and causes, of whom the average course was 90.6±115.2 days. The most common cause was leucocoria in 32 patients (62.7%), followed by redness and swelling in 4 patients (9.8%), and other causes in 5 patients (12.2%). Among the 15 re-visiting patients, the average diagnostic age was 63.6±46.8 months, the average course was 32.8±45.5 months. Recurrence was occurred in 5 patients (33.3%), leucocoria in 4 patients (26.7%), postoperative complication in 3 patients (20.0%), protrusion in 2 patients (13.3%) and redness in 1 (6.7%) patient, respectively. Fifty out of 82 eyes were admitted to hospital, including 37 eyes of first-visiting patients and 13 eyes of re-visiting patients. Among 37 first-visiting eyes, there were 5 eyes (13.5%) in stage A-C, 26 eyes (70.3%) in stage D-E, 6 eyes (16.2%) in extraocular stage. Five eyes in stage A-C were treated with laser photocoagulation and (or) cryotherapy combined with systemic chemotherapy. Four eyes in stage D were treated with intraocular arterial chemotherapy. Nineteen eyes (51.3%) were performed with enucleation, 2 eyes (5.4%) with evisceration and 7 eyes (18.9%) abandoned treatment. Among 13 re-visiting eyes, 6 eyes (46.2%, with 5 eyes of recurrence) had been enucleated before, 4 eyes (30.8%) were in extraocular stage and 3 eyes (23.1%) in stage D-E. Five eyes (38.5%) were treated with evisceration, 4 eyes (30.8%) with enucleation, 1 eye with oculoplastic surgery and 3 eyes (23.1%) abandoned treatment. The rate of eye preservation was 18.0%, 29.0% for intraocular stage and 0% for extraocular stage, respectively.ConclusionRB patients in Southwest China have a longer course between onset symptoms and diagnosis, more advanced classification and lower rate of eye preservation.

Objective To observe the fundus characteristics of human immunodeficiency virus with acquired immune deficiency (HIV/AIDS). Methods A total of 1041 HIV/AIDS patients were enrolled in this study. The patients included 882 males (88.70%) and 159 females (11.30%). The patientsprime; ages ranged from 12 to 73 years, with a mean age of 41 years. The median time of HIV/AIDS diagnosis was 12 months, which ranged from one month to 10 years. HIV infection was acquired through sexual contact, intravenous drug use, blood transfusion or mother-to-child transmission in 475 patients (45.63%), 508 patients (48.80%), 44 patients (4.25%) and 14 patients (1.34%), respectively. Ocular examinations (vision acuity, slit lamp microscope and fundus examination) were performed on recruited patients with HIV/AIDS. Additional exams (intraocular pressure, fundus photography and fundus fluorescein angiography) were done if abnormal ocular fundus was found. The ocular manifestations were diagnosed according to clinic reference. Results Ocular manifestations of HIV/AIDS were detected in 247 patients (23.73%). Of 247 patients, the most common ocular manifestation was HIV retinopathy, which was present in 132 patients (53.44%); cytomegalovirus retinitis (CMVR) was second place, affecting 70 participants (28.34%). Clinic findings of HIV retinopathy included retina microaneurysm, hemorrhage along the blood vessel with cotton-wool spots, while irregular dry edge, granular appearing border, were present in CMVR, and the optic nerve may be affected. Fluorescein angiogram of HIV retinopathy demonstrated that hemorrhage was shown as sheltered fluorescence, with b fluorescence without leakage in center of hemorrhage. Fluorescein angiogram of CMVR demonstrated significant hemorrhage appearing as sheltered fluorescence with leakage and/or transparent fluorescence. The optic disk and lesioned area were stained with fluorescence. Conclusions There are various HIV/AIDS related ocular manifestation. HIV retinopathy and CMVR are common ocular manifestations. The main clinical findings of HIV retinopathy are hemorrhage and/or cotton-wool spots, while irregular granular appearing edges and hemorrhage were observed in CMVR.
Objective To investigate the clinical characteristics of patients with polypoidal choroidal vasculopathy (PCV) from Central China . Methods This was a retrospective study, and 403 eyes of 362 patients diagnosed as PCV by ocular fundus photography, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optical coherence tomography (OCT) were enrolled. The general clinical data, fundus manifestation and ocular fundus examinations were statistically analyzed. Results Three hundred and sixty-two cases included 249 males (68.8%) and 113 females (31.2%). Age ranged from 45 to 91 years old, and mean age was (64.81plusmn;9.31) years old. Bilateral lesions were observed in 41 patients (11.3%) and unilateral lesions were observed in 321 patients (88.7%)． In these 403 eyes, typical orangered lesions were observed in 162 eyes (40.2%); yellowishwhite exudate could be found in 185 eyes (45.9%); 268 eyes (66.5%) showed variable degrees of subretinal hemorrhage. Drusen was found in 23 eyes (5.7%), pigment proliferation in 20 eyes (5.0%) and fiber vascular scar in 96 eyes (23.8%). The lesions of 386 eyes (95.8%) located in macular region, 53 eyes (13.2%) in peripapillary area. Lesions presented multifoci in 67 eyes (16.6%). Three hundred and four eyes (75.4%) presented typical polypoidal lesions and 152 eyes (37.7%) with abnormal branching choroidal networks. Hemorrhagic retinal pigment epithelial detachments (PED) were found in 200 eyes (49.6%) and serous PED in 96 eyes (23.8%), both existed in 25 eyes（6.2%）. OCT showed 56 eyes (13.9%) presented cystoid dark chamber between the neurosensory retina and 109 eyes (27.0%) with double-layer sign formed by the separation of retinal pigment epithelium and Bruchprime;s membrane (27.0%). Two hundred and seventy-four eyes (68.0%) were found with conelike elevation beneath the RPE layer and 151 eyes (37.6%) with neurosensory detachment. Conclusions In Central China, the majority of PCV patients were male, unilateral. Most PCV lesions were located in the macula. Subretinal hemorrhage, polypoidal lesions and abnormal choroidal vascular networks were common in the PCV patients. Hemorrhagic PED presented a higher ratio than serous PED.
Objective To observe the fundus characteristics of acquired immune deficiency syndrome (AIDS) with human immunodeficiency virus (HIV) retinopathy. Methods Eighty eyes of 52 AIDS patients with HIV retinopathy were enrolled in this study. The patients included 42 males (67 eyes) and 10 females (13 eyes). The patients ages ranged from 16 to 78 years, with a mean age of (43plusmn;12) years. All patients' visual acuity, intraocular pressure, slit-lamp microscopy and mydriatic indirect ophthalmoscopy, fundus color photography and CD4+ T cell count was documented. Experienced ocular fundus doctors carried out fundus examinations. Retinopathy characteristics were recorded. Seventeen patients (24 eyes) were followed for a period between two days to two years, with a median of 125 days. We failed to follow up the remaining 35 patients (56 eyes) due to death or moving away. Results Among 52 patients (80 eyes), 28 patients (56 eyes, 70.0%) had bilateral HIV retinopathy and 24 patients (24 eyes, 30.0%) had unilateral HIV retinopathy. Cotton-wool spots (CWS), mostly located close to temporal peripapillary vessels, were found in 46 patients (72 eyes, 90.0%). Six patients (eight eyes, 10.0%) were found to have flaming or spotting hemorrhage located in posterior pole. Among 72 eyes with CWS, 57 eyes were found to have CWS only and 15 eyes were found to also have retinal hemorrhage, mostly located near CWS. Among 24 eyes of 17 followed-up patients, three eyes of three patients were found with no significant changes during the less than two week follow-up. In 18 eyes of 11 patients, CWS or hemorrhage disappeared after one to three months without treatment and in five eyes new CWS or hemorrhage were found in other parts of the posterior pole. Three eyes of three patients initially considered as lint plaque-like lesions were eventually detected with CMVR as lesions during one to five months follow-up. Conclusion CWS are the most common ocular lesions in HIV retinopathy.
Objective To compare neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV) in age at diagnosis, gender and disease laterality. Methods One hundred fourteen nAMD patients (114 eyes) and 145 PCV patients (186 eyes) diagnosed by fundus fluorescein angiography (FFA) and indocyanine green angiography were enrolled in this retrospective study. The age at diagnosis, gender and disease laterality of all the patients were collected. Independent sample t-test, chi;2 test and Fisher's exact test were used to compare the age at diagnosis, gender and disease laterality between nAMD and PCV patients. Results The mean age at diagnosis of nAMD group and PCV group were (68.30plusmn;9.86), (65.67plusmn;9.04) years respectively, the difference was statistically significant (t=-2.168, P=0.031). The patients under 70 years old accounts for 50.88% in nAMD group, which is lower than that in PCV group (63.45%), the difference was statistically significant (chi;2 =4.138, P=0.042). The male/female ratio of nAMD group and PCV group were 3.56∶1 and 2.02∶1 respectively, the difference was statistically significant (chi;2 =3.937, P=0.047). Thirty patients (26.32%) and 41 patients (49.46%) were affected unilaterally in nAMD and PCV group, respectively. The difference of bilateral incidence between two groups was not statistically significant (chi;2 =0.123, P=0.726). There were 69 right eyes (47.92%) and 75 left eyes (52.08%) in nAMD group, 92 right eyes (49.46%) and 94 left eyes (50.54%) in PCV group. The difference of disease laterality between two groups was not statistically significant (chi;2 =0.078，P=0.637). Conclusions PCV patients present at younger age than nAMD. nAMD is more prone to affected males than PCV. Nearly a quarter patients are bilateral in nAMD or PCV, there is no difference in bilateral incidence between these two diseases.
Objective To observe the ocular features and analyze the cause of misdiagnosis of intraocular nonHodgkin's lymphoma (IONHL). Methods A retrospective study was performed in 6 patients and related literatures were reviewed. The age of those patients was 46 to 68 yrs with an average of 562 yrs. Four cases were female, two cases were male. Five patients were unilateral and one case was bilateral case. All patients were investigated by Goldmann tonometer, fundus fluorescein angiography (FFA) and ophthalmic Bscan. Pathological samples come from enucleation and vitrectomy, and were analyzed histologically and immunohistochemically. Results Ophthalmological signs of IONHL included decrease visual acuity, red eye, aqueous flare; keratic precipitates (Kp), vitreous opacity, retinal detachment and multiple whiteyellow retinal lesions of different sizes and fuzzy boundaries. IONHL patients were always misdiagnosed as diverse and nonspecific symptoms and signs, two cases were misdiagnosed as retinitis or chorioiditis, one case as intermediate uveitis, one case as secondary glaucoma in uveitis. The duration from onset of symptom and sign to a final diagnosis was from 6 months to 24 months with an average of 13.3 months. Conclusions The clinical manifestation of IONHL was diverse and non-specific，and this disease was unknown to lots of doctors and easily be misdiagnosed.
