Optic disc drusen (ODD) is an acellular deposit located in front of the cribriform of the optic disc. ODD has been much underdiagnosed due to few obvious clinical symptoms. These clinical symptoms are easily confused with optic disc edema caused by systemic high-risk diseases. The current mainstream view is that optic nerve fiber axon metabolism is disordered, leading to intracellular mitochondrial calcification. After axon chronic disintegration, calcified mitochondria continuously release outside the cell, resulting in a much higher concentration of extracellular calcium than inside the cell. The continuous deposit and accumulation of extracellular calcification fuse to small calcified corpuscles, which lead to ODD formation. OCT enhanced deep imaging can detect ODD sensitively, and its image feature is a weak reflection core completely or partially surrounded by a strong reflection edge. ODD is one of the common causes for optic disc crowding. During adolescence, the accumulating calcified bodies buried in the deep optic disc gradually extrude and migrate to the superficial optic disc, which turn into superficial ODD. As a consequence, part of these ODD patients rapidly progress during adolescence and generally become stable in adulthood with anterior ischemic optic neuropathy, or other vascular complications.
【摘要】 目的 觀察激光、白介素-2、膦甲酸鈉聯合治療尖銳濕疣的療效。 方法 2007年1月-2009年4月將收治的412例尖銳濕疣患者隨機分為:A組140例采用激光治療，B組138例采用激光、白介素-2治療，C組134例在B組基礎上聯合膦甲酸鈉治療。 結果 C組的總有效率為97.7%，明顯高于A、B兩組，組間比較，有統計學意義（Plt;0.05）；且C組的復發率最低，為4.6%。 結論 激光、白介素-2、膦甲酸鈉聯合治療尖銳濕疣獲得較佳療效，且復發率低，值得臨床關注。【Abstract】 Objective To observe the effect of combinging laser, interleukin (IL-2) and foscarnet sodium on condyloma acuminatum. Methods From January 2007 to April 2009, 412 patients with condyloma acuminatum were randomly divided into three groups, 140 patients with single laser were in group A, 138 patients with laser and IL-2 were in group B, 134 patients with laser, IL-2 and foscarnet sodium were in group C. Results The total effective rate was 97.7% in group C, which was significantly higher than those in group A and B (Plt;0.05); and the recurrence rate was the lowest in group C (4.6%). Conclusion The combination of laser, IL-2 and foscarnet sodium has better efficacy and lower recurrent rate on condyloma acuminatum, it is worthy of spreading to application.
PURPOSE:To discuss the clinical characteristics and differential diagnosis of peripapillary subretinal hemorrhage(PPSRH). METHOD:Retrospective analysis of the clinical documents including mainly the ocular manifestations and the findings of fundus fluorescein angiography(FFA)of 37 patients (38 eyes)with PPSRH. RESULTS:In all of these 37 patients,36 were myopes, 31 were young persons ,the average age was 21 years old,and 36 were affected unilaterally. The subretinal hemorrhage revealed itself in 4 types :PPSRH (5 eyes),PPSRH with disc iaemorrhage (21 eyes),PPSRH with vitreous hemorrhage (2 eyes), and PPSRH with disc hemorrhage and vitreous hemorrhage (10 eyes). In the FFA, the hemorrhages showed blocked fluorescence and the optic discs showed irregular hyperfluorescence at the late phase. All of the hemorrhages were absorbed within 3 weeks to 3 months without any treatment. CONCLUSIONS:According to the manifestation of the optic discs in FFA PPSRH might be complicatton of the buried optic disc drusen. （Chin J Ocul Fundus Dis,1997,13: 143-145 ）
Age-related macular degeneration (AMD) is one of the leading causes of irreversible vision loss. There are two primary forms of AMD: exudative age-related macular degeneration (WAMD) and atrophic AMD (DAMD). While numerous medications are currently available for the treatment of WAMD, yielding significant therapeutic outcomes, effective treatments for DAMD remain scarce. Various animal studies and clinical trials on DAMD treatment have been conducted, focusing primarily on antioxidants, complement pathway inhibitors, mitochondrial protectors, visual cycle inhibitors, neuroprotectants, amphiphilic polymer-based drug delivery systems, cell therapy, photobiomodulation therapy, gene therapy, surgical interventions, and traditional Chinese medicine. Among these, antioxidant supplementation with vitamins and complement pathway inhibitor APL-2 and ACP have received Food and Drug Administration approval for the treatment of DAMD. With the continuous development of the medical field, the future will explore the treatment methods with little trauma, good efficacy and good patient compliance, and successfully achieve clinical transformation.
Objective To observe and estimate the image characters of indocyanine green angiography (ICGA) and fundus fluorescein angiography (FFA) in atrophic age-related macular degeneration(AMD) and macular drusen. Methods FFA, ICGA and fundus photography were performed on 95 eyes of 73 atrophic AMD patients, in cluding 19 patients (26 eyes) with depigmentation and atrophy of retinal pigment epithelium (RPE), 15 (30 eyes) with macular drusen, and 39 (39 fellow eye) with unilateral exudative AMD.Results In 26 eyes with depigmentation and atrophy of RPE, the result of FFA of 24 eyes with depigmentaion showed patch hyperfluore scence, and of ICGA showed patch hyperfluorescence and hypofluorescence on the late photographs; in 2 eyes with maplike atrophy of RPE, the result of FFA showed patch hyperfluorescence, and of ICGA showed choriocapillaris defect with sharply demarcated boundaries and hypofluorescence of large choroidal vessels. In 30 eyes with macular drusen, the result of FFA of 8 eyes with hard drusen showed hyperfluorescence, and of ICGA showed patch and spot hyperfluorescence; the result of FFA of 16 eyes with soft drusen showed hyperfluorescence, and of ICGA showed persistent patch hypofluorescence intermixed with cluster hyperfluorescence; and the result of FFA of 6 eyes with both soft and hard drusen showed hyperfluorescence, and of ICGA showed patch hyperfluorescence intermixed with hypofluorescence. When it was hypofluorescence in ICGA in patients with macular drusen, larger quantity and range of fluorescence were found in FFA than in ICGA; when it was hyperfl uorescence in ICGA, smaller quantity and range of fluorescence were found in FFA than in ICGA. In 39 fellow eyes of unilateral exudative AMD, 32 or 31 eyes, examined by ICGA or FFA, had abnormal fluorescence of drusen and depigmentation and atrophy of RPE damage.Conclusions Simultaneous examination of IC GA and FFA can be useful for accurate evaluation of fundus image characters of types of angiography in atrophic AMD.(Chin J Ocul Fundus Dis，2003，19：79-82)
目的:評價外用鹽酸氨酮戊酸散光動力療法治療尖銳濕疣的臨床療效。方法:采用開放、高頻電離子平行對照的臨床研究方法。治療組28例患者,采用外用鹽酸氨酮戊酸散光動力療法,一周治療一次,連續治療三周;對照組37例患者,采用高頻電離子切割治療。兩組患者均在末次治療后第一周進行療效評價及不良反應觀察,第4、8、12周觀察復發率。結果:1例患者因三次外用鹽酸氨酮戊酸散光動力療法后疣體脫落而提前終止試驗,64例患者完成了全部的隨訪。在末次治療后1周時疣體清除率:治療組為96.4%,對照組為100%,其中尿道口的疣體清除率:兩組均為100%;非尿道口的疣體清除率:治療組為91.67%,對照組100%,無論是尿道口還是非尿道口尖銳濕疣,兩組的療效無統計學差異(Pgt;0.05)。治療后隨訪12周的復發率:治療組為 6.86%,對照組24.32%, Plt;0.05;其中尿道口的復發率:治療組為 5.88%,對照組42.86%,Plt;0.05;非尿道口的疣體清除率:治療組為8.33%,對照組為20%,Plt;0.05。兩組均具有統計學差異。兩組均沒有出現系統不良反應,局部不良反應率:治療組為7.14%,主要為輕度糜爛、疼痛、滲液;對照組為4865%,主要為潰瘍、疼痛、疤痕等,治療組不良反應發生率均明顯低于對照組,差異有統計學意義。結論：ALA-PDT清除率高，復發率低，安全，耐受性好，無明顯副作用，可作為尿道口CA治療首選。
