Model newborn human eye and face manikin
View Patent ↗A model newborn human eye which includes a hemispherical-shaped, integrally molded top assembly comprising a visually transparent cornea portion surrounding a visually opaque sclera portion in combination with a hemispherical-shaped bottom assembly comprising a bowl-shaped substrate disposed therein. The model newborn human eye further comprises a retinal layer comprising a two dimensional image of retinal vasculature disposed on said substrate, where the model newborn human eye is dimensioned for diagnosing Retinopathy of Prematurity (“ROP”) in premature infants.
1. A model newborn human eye, comprising:
a hemispherical-shaped, integrally molded top assembly comprising a visually transparent cornea portion surrounding a visually opaque sclera portion;
a hemispherical-shaped bottom assembly comprising a bowl-shaped substrate disposed therein;
a retinal layer comprising a two dimensional image of retinal vasculature disposed on said substrate;
wherein:
said top portion is attached to said bottom portion to define a posterior chamber;
said model newborn human eye is dimensioned for diagnosing Retinopathy of Prematurity (“ROP”) in premature infants.
2. The model newborn human eye of claim 1 , wherein:
said a retinal layer comprises a three dimensional image of retinal vasculature disposed on said substrate; and
said model newborn human eye is dimensioned for surgically treating Retinopathy of Prematurity (“ROP”) in premature infants.
3. The model newborn human eye of claim 1 , wherein:
said a retinal layer is formed to include a subsurface fluid cavity therein; and
said model newborn human eye is dimensioned for practicing optical coherence tomography to locate and photograph said subsurface fluid cavity.
4. A method to practice diagnosis and treatment of Retinopathy of Prematurity (“ROP”) in premature infants, comprising:
providing a model newborn human eye dimensioned to mimic an average newborn human eye and comprising a hemispherical-shaped, integrally molded top assembly comprising a visually transparent cornea portion surrounding a visually opaque sclera portion, a hemispherical-shaped bottom assembly comprising a bowl-shaped substrate disposed therein, and a retinal layer disposed on said substrate and comprising retinal vasculature;
providing a newborn face manikin formed to mimic a newborn/neonatal human face comprising a raised, face-mimicking structure comprising an eye socket extending there through;
releaseably disposing said model newborn human eye in said eye socket such that said cornea portion extends outwardly from said eye socket.
placing a hand held camera on the cornea interfaced with an ophthalmic lubricant; and
scanning said retinal vasculature for abnormal blood vessels.
5. The method of claim 4 , further comprising performing a peripheral retinal ablation using a solid state laser photocoagulation device to destroy avascular portions of the periphery of the retinal layer.
6. The method of claim 4 , further comprising inserting a probe to briefly touch and freeze spots on said retinal vasculature.
7. The method of claim 4 , wherein said top portion and said bottom portion define a posterior chamber, and wherein said posterior chamber is filled with a vitreous gel, comprising:
removing said vitreous gel;
peeling back scar tissue on said retinal layer.
8. The method of claim 4 , further comprising:
placing a silicone band around said model newborn human eye;
tightening said silicone band; and
causing the sclera to buckle towards said retinal layer.
9. The method of claim 4 , further comprising:
determining if retinal hemorrhaging can be observed;
when retinal hemorrhaging is observed, determining if said retinal hemorrhaging is bilateral;
when said retinal hemorrhaging is bilateral, determining if flame-shaped hemorrhages can be observed;
when flame-shaped hemorrhages can be observed, determining that child abuse should be highly suspect.
10. A method to practice Optical Coherence Tomography (“OCT”) to obtain surface and subsurface images of the retina, comprising:
providing a model newborn human eye dimensioned to mimic an average newborn human eye and comprising a hemispherical-shaped, integrally molded top assembly comprising a visually transparent cornea portion surrounding a visually opaque sclera portion, a hemispherical-shaped bottom assembly comprising a bowl-shaped substrate disposed therein, and a retinal layer comprising a three dimensional retinal vasculature disposed on said substrate;
directing an optical beam at the retinal layer;
using interferometry record an optical path length of received photons;
collecting light directly reflected from retinal layer surfaces.
11. The method of claim 10 , wherein said retinal layer is formed to include a subsurface fluid cavity formed therein, comprising imaging 1 to 2 mm below a surface of said retinal layer to image said subsurface fluid cavity.
