Abstract Details


To describe results of demarcation laser photocoagulation in preventing progression of subclinical retinal detachment (SCRD).


Dokuz Eylul University School of Medicine, Izmir, Turkey.


Eleven patients, with 12 eyes involved with 14 separate areas of subclinical retinal detachment (SCRD). Ages at initial diagnosis ranged between 27 and 73 years (mean 57.33±13.80). Periodic retinal examinations over follow-up periods of between 6 months and 60 months, using Goldmann three-mirror contact lens and sometimes semilunar mirror lens with scleral indentation.


Eight patients (66.7%) were female, three (33.3%) were male. Of the 12 eyes involved, seven were right eyes and five were left eyes. One patient was affected bilaterally, and two eyes each contained two separate areas of involvement. The location of the SCRD was superior in 8 areas, and inferior in 4 areas; 8 were located temporally, and only 4 nasally. Four patients (36%) were found to have myopia greater than −3. 0 diopters. During follow-up period, clinical retinal detachments developed in two of the 12 eyes (16.7%) that had undergone pars plana vitrectomy. No complications were observed with laser photocoagulation.


Demarcation laser photocoagulation should be kept in mind in terms of first-line treatment for eyes with SCRD. Laser photocoagulation is vital in preventing progression to rhegmatogenous retinal detachment in most patients. After this treatment, these patients should be followed closely.
