Abstract: :
Purpose: To analyze the clincial characteristics of Type II juxtafoveal retinal telangiectasia and correlate visual acuity to stage of disease. Methods: A retrospective search of the Vanderbilt photographic database for the diagnosis of idiopathic type II retinal telangiectasia was done. Results: Sixteen patients consisting of 8 males and 8 females were included in the study. The age ranged from 41-72 years, with a mean age of 60.5 years and median of 55 years at presentation. The visual acuity ranged from 20-15- 2/200. Two of 32 eyes had Stage I disease with median visual acuity of 20/20. None of the patients had Stage II disease. Thirteen of 32 eyes had Stage III disease with a median visual acuity of 20/50, (range 20/15 - 20/70). Nine of 32 eyes had Stage IV disease with median visual acuity of 20/60 (range 20/25-20/80). Eight of 32 had Stage V disease with median visual acuity of 20/300 (range 20/60 - 2/200). In addition we found 5/32 eyes with outer lamellar hole with median visual acuity of 20/70 (range 20/40-20/70). One patient with functional visual loss was excluded for visual acuity correlation. Conclusion: Severe visual loss was found to correlate with occurrence of choroidal neovascular membrane. Most patients with stage 4 disease or lower, maintained moderate visual acuity. In addition, the presence of outer lamellar hole in stage 3 disease shifted the median acuity from 20/50 to 20/70.
