[Transpupillary thermotherapy for occult CNV in patient with age-related macular degeneration]

Purpose: to evaluate the effect of transpupillary thermotherapy on visual improvement and regression of occult choroidal neovascularization [CNV] in patients with age-related macular degeneration

Methods: thirty eyes of 30 patients with CNV who underwent thermotherapy by means of diode laser [lamda= 810 nm] were studied. Visual acuity, regression of neovascularization, funduscopy, and angiography were evaluated after 6 weeks, 3 months and 6 months

Results: out of 30 patients, 8 cases were female and 22 cases were male. Mean age was 67.3 years. After a mean follow up of 5.3 months, mean visual acuity improved from 1.25 log MAR [20/320] preoperatively to 1.06 log MAR [20/200] postoperatively which is equivalent to 2 lines of improvement in visual acuity [P< 0.004]. Anatomic success [choroidal atrophy or flat scar] was achieved in [73.3%] and failure [disciform scar or recurrent CNV] occurred in 26.7% [P= 0.0001]. Twelve cases of pigmented epithelial detachment [PED] including 2 cases of very large PED, responded to safe treatment perfectly

Conclusion: transpupillary thermotherapy may cause regression of choroidal neovascularization in age-related macular degeneration

investigation of the frequency of Persian typographical mistakes of MS and MD students in the faculties of medicine and dentistry

In scientific meetings, researchers present their research findings specially those derived from their dissertations. The scientific identity of the universities depend on the quality of these scientific documents. The more the principles of writing are observed in these dissertations, the more easily and fluently the writer's message is transferred to the readers. This is a descriptive study in which the mistakes in MS and MB students' dissertations were classified into five groups: spelling grammar, puncutation, organization and content. The data were anayzed by descriptive statistics. 18.92% of mistakes were typographical. In 13.61% of cases Hazmzeh was not written correctly. The most frequnet mistake was organizational and the least frequent one was grammatical. The findings revealed that in order to improve the quality of dissertations, students should pay more attention to spelling of words, punctuation, how to write Hamzeh, whether to connect the letter [B] to the noun or verb and whether to connect two words or not
