ImageJ assessment of double-frequency YAG laser efficacy in treatment of mild lower eyelid ectropion with punctal eversion.

PURPOSE: To describe a simple and minimally invasive technique using double-frequency YAG laser for correction of mild medial lower eyelid ectropion with punctal eversion and assess the efficacy of the technique by measuring the tear film meniscus pre- and post-laser treatment using imageJ software. METHODS: This study included 23 eyes of 19 patients with lower eyelid ectropion with punctal eversion. All patients were treated by double-frequency YAG laser applied to lower medial conjunctiva. Tear film thickness was assessed using imageJ software pre- and post-argon laser treatment. RESULTS: There was a highly significant change detected after argon laser treatment as regarding the mean of the height of tear film which was found to be significantly lower after argon laser treatment compared to before it (81.1 pixels versus 193.1 pixels, respectively) (P < 0.001). CONCLUSION: Double-frequency YAG laser applied to lower medial palpebral conjunctiva is a simple, easy, safe, and effective procedure which can be used as a solo treatment in early cases of punctal eversion with no or mild medial canthal tendon laxity.

Drain fluid cryo-explant technique for treatment of superior bullous rhegmatogenous retinal detachment in young adults.

PURPOSE: To evaluate the efficacy of the drain fluid cryo-explant (DFCE) technique for the management of uncomplicated superior bullous rhegmatogenous retinal detachment (RRD) in young adults. PATIENTS AND METHODS: A retrospective study that included eyes with uncomplicated superior bullous RRD in patients ⩽40 years old. DFCE technique consists of sequential drainage of subretinal fluid, intravitreal fluid injection, cryotherapy, and placement of a scleral explant(s). The primary outcome measure was anatomical reposition of the retina after a single surgery. Secondary outcome measures included improvement in best corrected visual acuity (BCVA) and any reported complication related to the procedure. RESULTS: The study included 51 eyes which met the study eligibility criteria. The mean duration of detachment was 19.7 ± 6.4 days. A single retinal break was found in 31 eyes (60.8%), and more than one break were found in 20 eyes (39.2%). The mean number of breaks per eye was 1.72 ± 1.04. The mean detached area per eye was 7.21 ± 3.19 clock hours, and the macula was detached in 22 eyes (43.1%). Flattening of the retina and closure of all retinal breaks was achieved in all eyes after a single surgery. Late recurrence of retinal detachment occurred in two eyes (3.9%) due to proliferative vitreoretinopathy (PVR). No complicated cataract or iatrogenic retinal breaks were detected in all eyes. CONCLUSION: DFCE technique could be effectively used for treatment of uncomplicated superior bullous RRD in adults ⩽40 years. It is safe and provides good visualization during surgery with no iatrogenic retinal breaks or complicated cataract.
