Abstract Details

Purpose:

To explore corneal venting incisions as a treatment option in a patient with persistent descemets detachment post phacoemulsification.

Setting:

Department of ophthalmology UCMS and GTB hospital Delhi India

Methods:

anterior chamber paracentesis was performed with a 23-gauge needle at 9 o’clock of the limbus, where the Descemet’s membrane remained in contact. After expressing out some aqueous humor by gently depressing the posterior lip of the paracentesis, the anterior chamber was filled with air. another paracentesis was made with a 23-gauge needle at 5 o’clock of the peripheral cornea as a venting incision, which was the highest point of the detached Descemet’s membrane, The needle stopped as soon as it penetrated the corneal stroma. Sterilized air was again injected into the anterior chamber.

Results:

Postoperatively, the edema reduced with DM reattached. Seven days after the descemetopexy, the patient’s Descemet’s membrane was completely reattached to the stroma and her BCVA had improved to 5/60. IOP was recorded as less than 21 mmHg during the follow-up. The patient was then discharged and followed up 1 month later in her local hospital. No re-detachment event was reported.

Conclusions:

DMD is one of the uncommon but serious complication post cataract surgery. The management depends upon various factors such as the area and the location of the detachment. Although, there has been reports of spontaneous resolution of DMD, but the failure rate is high. Descemetopexy, anterior chamber injection of gas to reposition the detached Descemet’s membrane, is now well accepted for the management of post-cataract surgery DMD. Corneal venting incision can be taken as a last resort before going in for penetrating/endothelial keratoplasty.
