Hyphema*

Postoperative hyphema following cataract extraction surgery is not usually a serious complication and clears quickly in the most cases. Sutureless cataract surgery was reported to have less incidence of postoperative hyphema than conventional cataract surgery. We analyzed the incidence of postoperative hyphema in each group according to the depth and the length of scleral pocket incision in 500 eyes with the sutureless cataract surgery via superior incision during two years. One day after surgery, 90 cases(18.0%) had hyphema and most of them(74.4%) showed grade 1 severity. The incidence of hyphema was 23.0% in the deep incision group and only 11.9% in the superficial incision group(p<0.01). The percentage of grade 1 hyphema was 66.6% in the deep group and 92.6% in the superficial group, then severity was greatly reduced in the superficial incision group(p<0.01). The incidence of hyphema in the group of 7.0 mm in length was highest among the 6.0, 6.5, 7.0 mm groups(p<0.01), and the shorter the incision length, the milder the serverity of hyphema(p<0.01). The incidence of hyphuma was the lowest(6.2%) in the group of 6.0 mm in length and superficial incision, and it was the highest(28.5%) in the 7.0 mm in length and deep incisional group(p<0.01).

The objective of this study was to ascertain the elationship between the various ocular traumas and the change of pulsatile ocular blood flow[POBF] measured with Ocular Blood Flow Tonograph[OBF Laboratories, UK Ltd.]. We tested POBF with Ocular Blood Flow Tonograph 3 times repeatedly within 48 hours after trauma in the 33 ocular trauma patients.In all the trauma eyes, heart rate[HR]and intraocular pressure[IOP]were higher and pulse amplitude [PA], pulse volume[PV], POBF were lower than in all the fellow eyes.In the hyphema group, HR, IOP, PA, PV, POBF were higher, especially IOP and OBF%S.D.were statically significant, than in non-hyphema group.In the orbital fracture group, only POBF and OBF%S.D.were higher than those of in non-fracture group. Therefore, these results show the change of POBF after various ocularinjuries in the ocular trauma patients.The further studies to follow up the serial change of POBF are necessary.

The history of surgical treatment of cataract extends back at least Before Christ. In 1748 Jacques Daviel, French ophthalmic surgeon, was attempted to cataract extraction with modern operating techniques and since then development of operation methods, techniques and instruments were contributed to recovery of the loss of vision. Although the occurrence of during and postoperative complications of cataract extraction diminish, cataract complications still remain troublesome in the minds of cataract operators. The authors reported the result of hyphema in the many complications of cataract extraction for the 7 of the 47 eyes(42 cases), which were operated from January 1976 to August 1977, using the sex, types of cataract, age, methods of operation, onset and procedure.

The authors experienced a case of retinoblastoma in a two-year-old female who had recurrent hyphema and marked erythematous lid swelling. We treated her for orbital cellulitis and hyphema, but those lesions were not improved. Finally, we performed enucleation for confirming the etiology of a disease which was pathologically proven to be retinoblastoma.

PURPOSE: To evaluate the clinical significance of angle-opening distance 500 (AOD500) using ultrasound biomicroscopy (UBM) in the early stage of traumatic hyphema. METHODS: The participants of this study were 46 hospitalized traumatic hyphema patients. We measured the quantity of initial blood clotting using a slit-lamp and the range of angle recession, AOD500 using UBM and then reviewed the relationship between the two. RESULTS: The difference of AOD500 in the traumatic and the non-traumatic eye measured by UBM at admission increased significantly in the wider recessed angle group (p=0.008), but did not increase at a statistically significantly level in the larger initial blood clot grade group (> or =Grade 2). CONCLUSIONS: These results suggest that the measurement of the angle-opening distance of both eyes using UBM will aid in evaluating the range of angle recession in patients in the early stage of traumatic hyphema.

Rebleeding in traumatic hyphema may cause several complications in the affected eye, and specific treatment of recurrent hyphema is still not estabilished and only conservative medical treatments are used except for surgical evacuation of the clot in case of persistent high intraocular pressure. We treated longstanding recurrent hyphema patient unresponsive to conventional medical treatment, with viscoeleastic substance which was injucted into anterior chamber. A large dose(0.2CC) of viscoelastic substance sufficient to directly compress the anterior structures(Iris, ciliary body) was injected and subsequently it increased the intraocular pressur gradually. We assume that these tamponade effect by the viscoelastic substance and later intraocular pressure rise was responsible for the therapeutic effect. Thus, viscoelastic injection into anterior chamber in longstanding recu.rrent hyphema patient may be a useful treatment.

Authors have experienced 27 cases of traumatic hyphemas in our department for recent years. All the patients was taken systemic administration of Diamox as ocular hypotensives, prednisolone as anti-inflammatory agent and hemostatics, and antihistaminics for neutralize the histamin like substance which may emerge after vascular injury by trauma, without any surgical procedures or other medication. The result of treatment satisfactory as hyphemas were absorbed clerly within short period without any complication and visual deterioration.

1. A comparative studies of the effects of Varidase and Urokinase on the experimental hyphema produced by the injection of rabbits auto-blood were performed in 20 eyes. 2. Subconjunctival injection of each enzymes were perfomed 1 hour after production of hyphema, and thereafter repeated once daily for 10 days. 3. Varidase increased the rate of absorption of hyphema, but Urokinase had no effect. 4. No side reactions were observed following the subconjunctival injection of these enzymes.
