A new suturing method for the treatment of giant retinal tear.

We report a new method for suturing the retina to the ocular wall when this is required for treatment of retinal detachment due to giant retinal tear. After closed vitrectomy, one of two ski-shaped needles (2.8 mm long and 0.4 mm thick) with an 8-0 nylon thread is introduced from a 1.4 mm scleral incision in the pars plana, advanced under direct observation through the retinal flap, and led extraocularly to an appropriate site in the opposite ocular wall. The second needle is advanced similarly through the same scleral incision and exited from the opposite ocular wall. The thread is then tied extraocularly on the sclera. The retinas of two patients were successfully reattached using this procedure in combination with encircling and the use of SF6 gas and air.

Risk of retinal detachment in patients with lattice degeneration.

To determine the risk of retinal detachment in patients with lattice degeneration of the retina, we statistically analyzed the incidence of retinal detachment in these patients. The data of hospital patients with retinal detachment associated with lattice degeneration in Kumamoto Prefecture, Japan, in 1990 were collected. The prevalence of lattice degeneration in Kumamoto was reported to be 9.5% in 1980. Based on population data from the 1990 census, the cumulative incidence of retinal detachment associated with lattice degeneration was calculated in this study. Among 1,840,000 residents in Kumamoto, there were 110 patients with retinal detachment associated with lattice degeneration; 72 with detachment resulting from tractional tears (tears), and 38 with detachment from atrophic holes. The cumulative incidence of retinal detachment from atrophic holes was 1.5% at the age of 40 years; from tears it was 3.6% at the age of 80 years. The cumulative incidence of detachment from both atrophic holes and tears was 5.3% at the age of 80 years. The results of this study are useful for clarifying the natural course of lattice degeneration.

Air pump for retinal detachment with macular hole.

From 1984 to 1992, 128 eyes with substantial retinal detachment due to macular hole underwent vitrectomy at the Ideta Eye Hospital. In the first 76 eyes treated, air was injected by syringe after removal of the vitreous (group A); in the subsequent 52 eyes, air was injected by a pump while subretinal fluid was aspirated through the macular hole (group B). The rates of retinal reattachment after the first surgery were 63.2% in group A and 82.7% in group B (P < .05). Thus, using the air pump was more effective than air injection.
