Purpose: To evaluate the dermofat graft in the anophthalmic socket treatment. Methods: A retrospective study including 28 anophthalmic cavity carriers treated with dermofat graft was carried out. The patients were analyzed according to age, sex, socket contraction degree, first surgery performed, reason for graft choice, procedure's results and complications. The data were analyzed according to the frequency of occurrence. Results: Nineteen (67.8%) of the 28 analyzed patients were male. According to age the majority of patients were between 40 to 60 years old (13 patients - 46.4%) and the most common cause of eyeball loss was trauma (seven cases - 25%). Anophthalmic socket type III was the most frequently observed (32.1%). The evisceration was the first procedure in 13 cases, enucleation in 11 and skin graft was done in two patients. Two patients came to the service after evisceration and did not provide any information about the first surgery. The choice to use the dermofat graft was to replace volume at the socket of 12 patients (42.8%). Most of the patients (53.6%) had no complications and graft necrosis was the problem most frequently observed (32.1%). The surgery was considered good in 71.4% and not good in only 7.1%. Conclusion: the dermofat graft is an efficient and easy technique to reconstruct the anophthalmic cavity. The authors suggest this procedure must be introduced in the medical training services since it provide good results.

Este trabalho mostra os resultados obtidos com a realização de ensaios geofísicos na em áreas de lavra de areia, no município de Descalvado, SP. O objetivo dos ensaios é o de detectar cavidades no interior de arenitos, pertencentes às Formações Pirambóia e Botucatu. Estas cavidades formaram-se com o rebaixamento do lençol freático, necessário para as operações de extração da areia. As técnicas geofísicas utilizadas foram: gravimetria, eletrorresistividade (caminhamento elétrico dipolo-dipolo) e radar de penetração no solo (GPR). Na primeira etapa dos trabalhos foram utilizados a gravimetria e a eletrorresistividade em uma bancada onde ocorreu um desmoronamento devido ao abatimento do teto de uma cavidade. Os resultados obtidos com estas duas técnicas foram coerentes pois a gravimetria mostrou baixos gravimétricos indicando uma ausência de massa na área de influência da cavidade e o caminhamento detectou um esperado aumento de resistividade elétrica nesta mesma área. Na segunda etapa, com a realização dos ensaios de GPR em uma bancada próxima à anterior, foi possível detectar cavidades por meio das feições hiperbólicas detectadas nos radargramas.

The implants are usually used after removal of the eye or its internal content, in order to maintain the orbital volume or, as in medicine, provide also the subsequent placement of ocular prosthesis. Considering prosthetic surgery procedures of high relevance in human and veterinary ophthalmology, this paper seek to review the main types of implants described in national and international literature, as well as describe the main complications when they are used in humans and veterinary patients.

The aim of this study was to establish mean values for intraocular structures and analyse if the differences are present for different skull conformations in dogs. In this study, 30 dogs were selected and distributed into three groups according to skull conformation; thus, group 1 (G1) was composed of brachycephalic dogs, group 2 (G2) was composed of mesocephalic dogs and group 3 (G3) was composed of dolichocephalic dogs. A and B-mode ultrasound was performed simultaneously for obtainment of measurements relating to anterior chamber depth (D1); lens thickness (D2); vitreous chamber depth (D3); and the axial length of the eye (D4). No differences were observed when comparing left and right eyes of dogs within the same skull conformation group (p>0.05). Differences were observed when comparing D3 and D4 between groups G2 and G3 (p<0.05). Skull conformation of brachycephalic dogs did not influence intraocular measurement values when compared to dolicephalic and mesocephalic dogs. Skull conformation of dolichocephalic dogs had an influence in values of vitreous chamber and the complete length of the eye when compared to mesocephalic dogs.
